In its "Independent Insight: U.S. Technology Strategy" report released Monday, Goldman Sachs predicts that IT spending growth in 2008 will drop to 4 percent from a former projection of 6 percent and that pricing pressure on vendors is going to get worse.

The good news, however, is that Goldman Sachs doesn't see IT spending levels dropping to their 2001-2002 or 1990-1991 levels due to more rational IT spending from 2003 to 2007. In other words, we have don't have as far to fall. The even better news if you're open-source vendor Red Hat? Shrinking IT budgets are your friend.

Where will IT dollars likely go? According to Goldman Sachs, hardware spending has likely already been cut as much as it's going to be, leading enterprises to look to save money with internal IT staff cuts and lower spending on services. Services, however, are more likely to be cut for onsite services, with 50 percent of Goldman Sachs survey respondents indicating that they will be cutting services budgets: offshore services are expected to remain relatively strong.

Not everyone is losing out in the downward economy, of course. Goldman Sachs sees growing enterprise interest in Apple's iPhone, for example. Software, too, may be a moderately bright spot:

In general, indications of software spending are marginally better than for overall tech spending, while indications for spending with Oracle looked better still. Linux is still making headway in the enterprise, with our responses showing Red Hat's dominance may actually be growing. A first read showed a meaningful proportion [21 percent] of respondents planning to test Google apps, a negative for Microsoft longer term.

Not surprisingly, Red Hat is the dominant Linux server operating system used by enterprises, with over 80 percent pointing to Red Hat as their primary Linux distribution. Suse Linux tends to serve more often as a second source, according to our panel. Perhaps more interesting, Red Hat is most often pointed to as continuing to gain share within users' environments (44 percent of applicable respondents indicating). On the flip side, Suse is the Linux server OS most often pointed to as losing share within users' environments (26 percent).

I suspect that as much as Oracle's broad-based approach is helping it win market share, Red Hat's singular focus on Linux and JBoss is strengthening its hand against Novell, which perhaps dilutes its Linux focus with a range of other products only tangentially related to Linux. Even so, Novell's Linux business has been seeing strong growth lately.

Market share, brand, and size are critically important in a slowing economy, as the report notes. Pricing discounts are becoming ever more aggressive as vendors seek to hold up demand even as budgets shrink, which Goldman Sachs believes favors "larger solution providers that can offer attractive pricing and payment terms on bundles of products relative to smaller "best-of-breed" vendors that may lack similar flexibility." The other group it benefits? Open-source vendors with no need to discount aggressively because 100 percent license discounts are already built into their product pricing.

All in all, it's a fascinating report and a sobering glimpse into near-term IT spending. The big consolidators are winning, but so is the industry's dominant open-source vendor, Red Hat.
